From: Graded motor imagery for women at risk for developing type I CRPS following closed treatment of distal radius fractures: a randomized comparative effectiveness trial protocol

The patient must:
1. Have continuing pain, which is disproportionate to any inciting event
2. Report at least one symptom in three of the four following categories:
 • Sensory: reports of hyperesthesia and/or allodynia
 • Vasomotor: reports of temperature asymmetry and/or skin color changes and/or skin color asymmetry
 • Sudomotor/edema: reports of edema and/or sweating changes and/or sweatingasymmetry
 • Motor/trophic: reports of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)
3. Display at least one sign at time of evaluation in two or more of the following categories:
 • Sensory: evidence of hyperalgesia (to pinprick) and/or allodynia (to light touch and/or deep somatic pressure and/or joint movement)
 • Vasomotor: evidence of temperature asymmetry and/or skin color changes and/or asymmetry
 • Sudomotor/edema: evidence of edema and/or sweating changes and/or sweating asymmetry
 • Motor/trophic: evidence of decreased range of motion and/or motor dysfunction (weakness, tremor, dystonia) and/or trophic changes (hair, nail, skin)
4. Not have another diagnosis that better explains the signs and symptoms
